sArnry-carorrron PINS AND SIMILAR ARTICLES. 7

T 0 all 107L017; it may concern Be it known that I, ARNOLD ScHRonT'rnR, a citizen of the United States, and resident of the borough and county of the Bronx, city and State of N evrYork, have lnvented certain new and useful Improvements in Safety Catches for Pins and Similar Articles, of which the, following is a specificay tion.

My invention relates to catches whereby the fastening pin or brooches, breast pins,

' and similar articles are intendeclto be locked in position, and has for its object to provide a simple constructionv which includes the various novel featuresofimprovement pointed out in the specification and set forth in the appended claims.

In the accompanying drawings, whichf illustrate a specific embodiment of the 1nvention without defining its limits, Figure 1 is a rear View of an open-work bar pin provided with my invention; Fig. 2 is a plan view thereof; Fig. 3 is an enlarged de-.

tail cross-section on the line 3--3 of Fig. 4;

Fig. 4 is an enlarged detail longitudinal section on the line 4l of Fig. 3; Fig. 5 is an end View; Fig. 6 is afragmentary front. View and Fig. 7 plan View. I

The catch comprises a hook-shaped mem} which is c'urvedtransversely as indicated, in Figs. 3 and 5, and longitudinally as shown in Figs.

4; and 7, said hood being extended somewhat beyond the shank 12 of the member 10 to form a projecting abutment 13. The shank 12 is forked to form a pair of bendable prongs i lflconstituting a bridge which is located in a plane transverse to the plane of the hook-shaped member 10 or which e2;-

7 tends in a direction lengthwise of the usual fastening pin referred to later on, as shown in Fig. 4. These prongs 14 are arranged to be fastened to an article for attaching the catch thereto, andin the case of an openwork bar pin or the like 15, such as shown in the drawings, may be brought into registry with the solid parts or webs thereof and soldered or otherwise connected therewith.

By having the prongs located in a planev transverse tothe attachment thereof to the pin of the illustrated type or its equivalent'is facilitated as in this position the prongs are more readily brought into registry with solid partsot the Specification of Letters Patent.

In practice the usual resilient or springy fastenlng pin :16 previously mentioned and which is pivoted at 17 to thebar pin 15 or other article sarranged to be engagedfwitlr the hook 10 in the manner-to bemore fully described hereinafter.

The shank '12 is formedwith slot e recess l8 which extends into the memberio and accommodates a locking member or.

keeper 1%) which is pivoted at 20 "and is pro; v ded with a finger-piece 21 as shown in F igs. 3 and 5, said locking memberbeing slltted at 22 to form a resilient iawi23 preferably l '2 i I ncluding as anintegral part thercof, acam 24:.

r In practice, after the brooch, pin or oth er' article "15 has been attached in place by meansof the fastening pin 16, the pointed end of'the' latter is brought beneathjthe hook-shapedmember 10 or more specifically the hood llthereof.v The parts are so 10-" cated and proportioned that in this position the pointed end of said pin. 16 willbear against the projecting abutment13, butprefgthat sectionof the pin 16 located between a erably not against the hood 11 at the point a v as shown in Fig. 4; this is not arbitrary asin some cases it. may be desirable to have the pin 16 also engage the hood 11 at the point a,

and 13,,in'any case, being free from contact with said hood. As the locking member or keeper 19 is pivotally moved" from the inoperative position shown in Fig. 5 to the operative position illustrated in Fig. 3, the

cam 24 will engage the pin l6 andas the pivotal movement is continued, will pass the latter, which finds a seat behind said cam, as shown in Fig. 3. The partsare so proportioned that the locking member or keeper I 19, or rather, that part thereof immediately behind said cam 24 flexes said pin 16 or, inf

other words places same under a resilient tension either between the abutment-13 and the pivot 17 or between said abutment with the point a, of the h'ood'll. In either-case,

the pin 16 is firmly-locked beneath the hook I 10 by the elastic tension under which; the

pin is placed and the resiliency of the j'awl2-3 I and by reason of the same forces, thelocking member 19 is held against unintentional-1i tion the cam 24 alsoprevents such .unin'te n pivotal movement out of. its operativejposr' I10 tionalmovement of the member 19.J To un-: lockthe' p1n'16, pressure is exerted on the finger-piece 21 in a direction to force the cam 24: outwardly beyond the pin 16 and to pivotally swing the member 19 to the inoperative position shown in Fig. 5.

A catch constructed as described may be easily applied to a brooch, pin or other article and may be readily manipulated;

when in operative position, the catch efiiciently'locks the pin against accidental or laroenous 'withdrawal and thus effectively guards the jewelry or other article against loss Without in any way complicating its le itimate removal.

xing beneath and bridging the longitudinal arch of said hood without contacting therewith-and engaging said hood only at a terminal point of said arch and a locking device movably carried by said member and arranged to engage said pin at a point vbetween the terminals of said longitudinal arch and thereby flex said pin against the resistance offered by saidhood at the point where it engages said pin whereby the latter is locked against unintentional removal from beneath said hook-shaped member.

2. The combination of an attaching pin, a hook-shaped member terminating in a forked bridge extending in a direction lengthwise of said pin and including'a hood, said pin extending beneath said hood and engaging same only inproximity' to its periphery, a locking-member pivotally mounted on said hook-shaped member and ar ranged to flex said pin against the resistance oflered by said hood where it engagessaid pin whereby the latter is locked against unintentional removal from beneath said hook-shaped member and a finger piece carried by said locking member for manipulating the same.

In testimony whereof I have hereunto set my hand. 7 c ARNOLD SGHROETTER.
